To all whom it may concern:

Be it known that I, LOUIS SCHOTTGEN, a citizen of the United States of America, residing in New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Delivery-Wagons for Fermented. Liquids, of which the following is i a specification.

This invention relates to an improved delivery-wagon for transporting and conveying formented liquids from the place of manufacture to the storage-tanks of the customer.

Heretofore fermented liquids, such as larger-beer and the like, were racked oil in the brewery into shipping-packages .and then shipped to the customer. This re uires the racking-01f of the beer or other liquid into the shipping-packages, the transportationof the same to the customer, the return of the packages to the brewery or other place of manufacture, and the washing and pitching of the packages for receiving a new charge of liquid.

This invention is designed to substitute.

for the present mode of racking-01f and shipping fermented liquids, a new system of shipment and delivery, which comprises a tank-wagon into which the beer or other fermented liquid is racked off and retained under pressure during transportation, and then drawn off at the place of business of the customer into dispensing-tanks of smaller size from which the liquid is drawn at the bar or counter under pressure.

The invention consists more specifically of a delivery-wagon which comprises a cylindrical. or other tank placed'on wheels, a piston in said tank, means for charging the tank and means for delivering the liquid fromthe tank, and means for supplying compressed air into the space at the interior of the tank between the piston and the adjacent head of the tank, as will be fully described hereinafter and finally pointed out in the claims.

Theinvention consists further of certain details of construction and combination of parts which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a. side-elevation of my improved delivery-wagon for fermented iquids,-shown as connected with the individual dispensingtanks in the cellar or basement of the customers for drawing off the liquid into said dispensing-tanks, Fig. 2 is a vertical longitudinal section of the tank of my improved delivery-wagon taken on line 2, 2, Fig. 3, Fig. 3 is a rear-elevation of the tank, partly in section on line 3, 3, Fig. 2, Fig. 4 is a vertical centralsection of the receiving-tank at the house of the customer, and Fig. 5 is a longitudinal sectional view, showing a modified construction of the delivery-tank and provided with two pistons 'so as to ship two different kinds of beer or fermented liquids at the same time.

Similar letters of reference indicate corresponding parts throughout the different figures of the drawings.

Referring to the drawings, 25 represents the tank of my improved delivery-Wagon, which tank is preferably made of cylindrical shape and of a sufficient size to contain from twenty to thirty barrels of lagerbeer or other fermented liquid. It is preferably made of porcelain-lined boiler-iron and supported on a wheeled frame, which is drawn either by horses or propelled by power. The tank is provided with heads h, 72, respectively at the front and rear end, which are connected by means of flanges and bolts and interposed packing with the ends of the tank, as shown clearly in Fig. 2. The heads are provided with hand-holes and covers for getting at the interior of the tank for cleaning the same. At the interior of the tank is arranged a sliding piston which keeps the liquid under pressure witfiout loss of gas. At the lower part of the rear-end of the tank t is arranged a nipple n which is connected by a hose with the storage-cask to be racked off, so that the liquid can'be charged under pressure intothe tank until the piston p arrives at the front-end of the tank and abuts by its flange-portion p against the front-head ll of the tank. T0 the head h of the tank is applied a nipple n which is connected by a hose 6 with an air supply-pump a, which is driven by a gasolene, electric or other motor m that is supported sidewise of the tank on the frame of the wagon. The tank is provided with two pressure-gages g, g},

one-for that part of the tank which 15 a charged with the fermented liquid and the other for that part of the tank which is charged with compressed air. The compressed air acting on the piston holds the fermented liquid always under pressure so as. to prevent the escape of any carbonic-acid I the tank is provided with a discharge-pipe n having a. stopcock a The dischargepipe n is provided at its inner end with a check-valve a. When the delivery-wagon arrives at the place of delivery, the discharge-pipe n is connected by a hosen with the dispensingtank 1' in the refrigerator of the customer, said dispensing-tank 1- being provided with a nipple n having a stopcock n and a weighted piston W. The piston-rod 79 of the piston 10 passes through the head of the tank and 1s provided at its upper end with an adjustable weight w so as to keep a certain amount of ressure on the liquid drawn off from the shipping-tank into the dispensing-tank. The dispensingtank is made large enough for receiving from one to ten barrels, aceordin to the quantity of liquid dispensed, per a but a number of dispensing-tanks may be arranged in the refrigerator of the customer, if required by him.

When the contents of the delivery-tank are discharged, after supplying a number of customers, and the piston arrives gradually near the rear-head of the tank, it is arrested in its motion by the inwardlyextending check-valve n of the discharge-pipe n valved air supply-pipe f, which extends horizontally along the outside of the tank from an opening in the front-head to an opening near the rear-head h is then opened, so that compressed air from the airspace inthe tank is transferred to the liquid in the space between the piston and the rearhead of the tank, so that all the liquid in the tank can be discharged. This supply-pipe for the compressed air is necessary as the piston cannot move beyond the check-valve n and could not force all the liquid out of the tank into the dispensing-tanks. f

The dispensingtank is connected with the bar or counter of the saloon or other place where the liquid is to be dispensed, which is done by means of a connecting-hose and by means of the pressure a plied by the weighted piston p to the liqui 1n the tank, the hose connecting the dispensingtank with the faucet of the bar or counter. The dispensing-tank takes the place of the ship-. ping-kegs and forms a permanent fixture in the place of the customer.

When the delivery tank is returned to the brewery or other place of manufacture, the interior of the tank is cleaned by washing the same with water supplied through the hand-holes in the heads, the piston being returned to its initial position near the front-head of the tank by introducing compressed air from the pump into the space formerly taken up by the liquid. For repairing the delivery-tank, the heads at both ends of the tank may be removed and a thorough cleaning and relining given to the interior of the tank. y

In Fig. 5 is shown a modification of the delivery-tank so as to permit-the shipping of liquids of different color or kind, such as light and dark beer and the like. In this case two pistons are arranged at the interior of the tank, with a space for the compressed air between the same. The supplypipe. for the compressed air is connected with the middle portion of the tank. A

safety-valve 12 is arranged for the air-space and two supply-nipples n and dischargepipes n at each end of. the tank. In other respects the working of the double tank is the same as the working of the single delivery-tank.

The quantityof liquid in the dispensingtank can be readily ascertained." The delivery-tank is provided at the inlet with a meter by which the quantity of liquid racked ofl' can be ascertained, and which issealed by a revenue ofiicer when the tank is filled, the seal being broken by the oflicer when the tank is to be filled again. The dischar e-pipe may also be provided with a meter or measuring the .quantity of liquid supplied to the various customers. By comparing the indicators on both meters the quantity of liquid still in the tank can be ascertained at an time.

The entire de ivery -tank may be surrounded in hot weather by means of ice, so as to keep the contents of the tank at a low temperature in hot weather while the liquid is in course of trans ortation.

The advantages 0 my improved shipping or delivery tank for fermented liquids are, first, that the large number ofshippingpackages, that is to say, half-barrels, quarters, sixths, etc., are dispensed with; second, that the cleaning and itching of the same on their return to the rewery is disensed with; third, that a considerable savmg of expense for labor in racking-01f,

are accomplished under pressure in a quick" and convenient manner and without the admission of any outside air; and, lastly, that the drawin -ofl of the liquid from the dispensing-tan s is greatly-simplified and facilitatedw I claim:

1. The combination of a tank, a piston in said tank dividing it into a s ace for liquid and a space for air, a 'valve sup 1ynipple for the liquid-s ace in the tank a valved discharge-pipe f dr the liquid, an air supply-pipe for charging compressed air into the air-space of the tank, and a valved airipe connecting the air-space with the liquid-space of the tank.

2. The combination of a tank, a piston in said tank, a supply-pipe for the liquid, a discharge-pipe for the llquid, means for supplying compressed air into the air-space of the tank at one side of the piston, and a valved air pipe connecting the air space with a point near the end of the liquid-space of the tank.

3. The combination of a tank, a piston in said tank dividing it into a space for liquid and a space for air, a valved supply-pipe for the liquid space, a valved dischargepipe for the same, an air supply-pipe for charging the air-space with compressed air, a valved air-pipe connecting the air-space with the liquid-space, a dispensing-tank at the place of dispensing the liquid, and a hose-connection between the discharge-pipe of the delivery-tank and the dispensing-tank. In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
